Maybe I have a stupid question but I did not find proper information on this forum or internet.

Currently I use serial gateway (Uno + NRF24 connected via USB, MyController) for connection of sensors. So sensors are arduinos (uno, mini, ...) with sensor and NRF24.

And now my stupid question. Can I connect WeMos D1 mini directly to my gateway (without NRF24)? Both items works on 2.4GHz.

Thank you for your reply

The short answer is no.
Both may use 2.4GHz as a physical transport layer, but the encondeing/decoding of the information is done completely different. You may compare that to two humans speaking, but one chinese and the other english - they may hear the other one producing sound, but will not be able to understand the message.

But is there a way how to connect ESP8266 to Controller. In MySensors are available just ethernet or serial gateway with NRF. Of course I can connect ESP to NRF and then use serial gateway but then there is no difference if I use ESP or nano.

If you plan to use a LCD screen, you may need a more powerfull MCU like the ESP or an STM32 (th later offering also more hardware SPI interfaces). There are some examples available you may use as a reference:https://www.mysensors.org/build/dollhouse#tv-nodehttps://www.mysensors.org/build/scene_controller

Just comment out "#define MY_RADIO_NRF24" in the example. Then present sensors and send data as you would on a normal node.
Add the gateway in your controller in the same way you would configure any other gateway.

In essence, you will have a tiny MySensors network consisting of just the MySensors gateway with locally attached sensors.
